HWACHEON HL-580 MANUAL LATHES

Technical Description

The Hwacheon HL-580 is a precision manual engine lathe engineered for general-purpose machining operations. This robust machine features a 23-inch swing over bed with a 59-inch distance between centers, accommodating workpieces up to 3.05 inches in spindle bore diameter. The lathe is powered by a 7.5 kW motor capable of delivering spindle speeds ranging from 28 to 1,350 RPM across 12 selectable speeds, enabling optimal cutting parameters for diverse materials and applications. The machine incorporates a high-precision 3-point support spindle with super-precision taper roller bearings and accepts either A1-8" or D1-8" spindle nose configurations. The MT #5 spindle taper and MT #7 spindle bore facilitate versatile tooling compatibility. With 40 feed changes available, the HL-580 delivers longitudinal and cross feeds ranging from 0.0014" to 0.0228" per revolution, enabling precise threading capabilities including inch threads (112–2 TPI), metric threads (0.0098"–0.55"), DP threads (8–112), and module threads (0.25–3.5). The machine's rigid cast-iron bed undergoes heat treatment and grinding for optimal shock and vibration absorption, while the dual-clamping tailstock with robust quill travel of 5.90 inches ensures secure workpiece holding and high-precision processing stability. Lever-operated carriage controls enhance user convenience, and integrated jog switching on the headstock facilitates operational flexibility. Weighing approximately 7,500 pounds with dimensions of 48" W × 149" L × 48" H, the HL-580 represents substantial, production-grade equipment suitable for tool rooms and job shops.
